Dispersant (Dispersant) yog ib qho tshuaj uas muaj ob yam ntxwv sib txawv, ob qho tib si lipophilic thiab hydrophilic. Cov khoom khov thiab kua uas nyuaj rau yaj hauv kua, kuj tseem tuaj yeem tiv thaiv kev sib sau ua ke thiab kev sib sau ua ke ntawm cov khoom me me thiab tsim cov amphiphilic reagent uas xav tau rau kev ncua ruaj khov.

Lub luag haujlwm ntawm cov tshuaj dispersant yog siv cov tshuaj dispersant ntub kom txo lub sijhawm thiab lub zog uas xav tau los ua kom tiav cov txheej txheem dispersion, ruaj khov cov dispersion pigment, hloov kho cov yam ntxwv ntawm cov xim, thiab kho qhov kev txav ntawm cov xim. Nws muaj cov hauv qab no:

1. txhim kho qhov ci ntsa iab, ua kom cov nyhuv ntawm kev sib npaug ntawm cov luster, qhov tseem ceeb tshaj plaws nyob ntawm qhov chaw ntawm lub teeb tawg (uas yog, qee qhov tiaj tiaj tuaj yeem ua tau., Tau kawg, yuav tsum txiav txim siab seb puas du txaus, tsis yog tsuas yog xav txog tus lej ntawm cov khoom me me, cov duab, thiab xav txog lawv cov kev sib xyaw), thaum qhov loj me ntawm cov khoom me me tsawg dua qhov teeb pom kev (tus nqi no tsis paub meej), kev ua tau zoo rau lub teeb refraction, luster yuav tsis txhim kho, tib lub zog npog vam khom rau qhov tawg muab lub zog npog tseem ceeb yuav tsis nce (tshwj tsis yog carbon dub feem ntau los ntawm kev nqus lub teeb, cov xim organic tsis nco qab). Lus Cim: lub teeb pom kev hais txog qhov ntau ntawm lub teeb pom kev tsis zoo; tab sis nco ntsoov tias qhov txo qis ntawm tus lej qub ntawm cov khoom me me yog kom txo qhov viscosity ntawm cov qauv, tab sis qhov nce ntawm qhov chaw yuav txo cov resin dawb, seb puas muaj qhov sib npaug, tab sis cov hmoov txheej dav dav tsis yog qhov nyias dua qhov zoo dua.

2. tiv thaiv kom cov xim plaub hau ntab.

3. txhim kho lub zog xim kom them sai sai rau lub zog xim hauv lub kaw lus hloov xim tsis siv neeg tsis yog qhov siab dua qhov zoo dua.

4. Txo qhov viscosity thiab nce cov xim.

5. txo cov flocculation zoo li no, tab sis qhov nyias dua ntawm lub zog ntawm cov khoom me me, qhov siab dua, qhov siab dua ntawm lub zog adsorption ntawm cov dispersant, tab sis lub zog adsorption ntawm cov dispersant yuav ua rau muaj kev cuam tshuam rau kev ua tau zoo ntawm cov zaj duab xis txheej.

6. Qhov laj thawj rau kev ua kom ruaj khov ntawm qhov chaw cia khoom zoo sib xws. Thaum lub zog ruaj khov tsis txaus, qhov ruaj khov ntawm qhov chaw cia khoom yuav phem dua (ntawm chav kawm, los ntawm koj daim duab).

7. ua kom cov xim pom tseeb dua, ua kom cov xim saturation ntau dua, ua kom pom tseeb dua (organic pigment) lossis npog lub zog (inorganic pigment).

HD605 cov tshuaj ua kom cov xim ntub thiab ruaj khov, tiv thaiv cov xim ntab thiab cov xim sib sau ua ke, tswj cov xim ruaj khov thiab lub zog xim thaum lub sijhawm khaws cia, thaum ua kom muaj xim ntau tshaj plaws thiab cov kauj ruam sib tsoo tsawg kawg nkaus. Vim tias cov tshuaj ntxiv no tuaj yeem txo qhov viscosity thiab nce mus rau qhov siab tshaj plaws ntawm cov xim thaum tawg, cov txheej thiab cov xim sib xyaw ua ke tsim tawm tau pheej yig dua. HD605 raug pom zoo rau kev tsim cov xim dej. Rau cov txheej txheem dej uas tiv taus corrosion, nws kuj yog cov khoom nyiam. Muaj peev xwm ua tau raws li qhov xav tau siab tshaj plaws ntawm lub zog optical thiab rheological. HD605 series yog cov khoom lag luam tus qauv uas twb muaj lawm tsis muaj ethoxyalkyl phenol rau ob qho tib si hom kuab tshuaj thiab cov mis dej. Hauv UV system, HD605 yog qhov tsim nyog rau txhua cov xim thiab cov khoom tsis muaj acetoxyalkyl phenol.
